Capacity and Compatibility

This kit provides 128GB of DDR4 memory across four 32GB UDIMM modules. It is validated for the Gigabyte TRX40 AORUS Xtreme motherboard and runs at 3200MHz with CL22 latency at 1.2V.

Installation Notes

The 288-pin unbuffered DIMMs install in standard desktop slots and require no special tools. Because there is no heat spreader, modules sit low but offer no thermal metalwork; ensure the board latches fully on both sides to avoid partial seating.

Pre-Purchase Checks

Verify your motherboard is the exact Gigabyte TRX40 AORUS Xtreme model and that the CPU supports quad-channel DDR4 at this speed. Confirm the BIOS is current enough for 2Rx8 density and that four slots are free for the full kit.
